This reflects a declining amount of fighting across populated areas in Syria, with the rebels expelled from the south, and a Russia-Turkey deal intended to prevent an offensive against the Idlib Province.

US airstrikes are also plummeting as well, with the loss of ISIS territory meaning more and more US warplanes are transitioning into Afghanistan. The civilian toll in Afghanistan, subsequently, has been rising substantially.

In September, the Observatory also documented the deaths of 436 rebels, 239 soldiers, and 236 jihadists. Nine other slain were unidentified. These too seem to be on the decline.
